Terrible experience. They didn't show up for our first "free estimate" appointment - apparently they went to the wrong state. We rescheduled and I got a call 10 minutes after our appointment time telling me they would be there in 20 minutes. Not a good start. When the salesman "John" finally got here I told him I had recently done the same thing with Power Home Remodeling and didn't want to go through a long presentation about window qualities, rather just get the estimate. He then proceeded to give his speech and demonstration of the windows. I cut him off several times explaining that I didn't want top of the line windows. His response was that I needed to do more research on windows and kept trying to show me high end windows. Then he claimed that if we spent say $20k on windows our home would be worth $20k more if a Realtor sold our house. I AM A REALTOR and this is not true! His response again was that I needed to do more research. At this point I told him to leave and he said that's okay I get $75 regardless for the visit. I would never use this company based on this experience. I was not listened to at all and felt disrespected by the salesman.
